发送消息之前转码为16进制
Java code
public static final String encodeHex(String msg) {
byte[] bytes = null;
try {
bytes = msg.getBytes("GBK");
} catch (java.io.UnsupportedEncodingException e) {
e.printStackTrace();
}
StringBuffer buff = new StringBuffer(bytes.length * 4);
String b;
char a;
int n = 0;
int m = 0;
for (int i = 0; i < bytes.length; i++) {
b = Integer.toHexString(bytes[i]);
if (bytes[i] > 0) {
buff.append("00");
buff.append(b);
n = n + 1;
} else {
a = msg.charAt((i - n) / 2 + n);
m = a;
b = Integer.toHexString(m);
buff.append(b.substring(0, 4));
i = i + 1;
}
}
return buff.toString();
}
